. Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed August 11, 1919. ,Serial No. 316,669.

To all 'whom t may concern Y Beit known that I, ADAM SGHAFER, a citi, zen of the` United States, residing at Sweet Water, iii the county ofMenard and State of Illinois, have invented anew and Vuseful Incubator, of which the following is a specil ication.

This invention relates to new and'uset'ul improvements in incubatore, and more particularly to incubators having circular egg trays.

Y vThe primary object of the invention is to provide exterior means for, rotating the egg trays simultaneously within the incubators, thereby moving certain eggs of the tray, from a pointnearest the source of' heat, to

Va position remote from the heating medium.

With the foregoing 4and other objects vin view which will appear.' as theV description proceeds, the invention resides in the combination and arrangement of parts andv in the details of construction hereinafter de'-l scribed and claimed, it being understood lthat changes inthe precise embodiment of the invention herein disclosed, may be'made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing- Figure 1 illustrates a top plan view of an incubator, constructed in accordance with Y the present invention, the cover or top thereof being removed.

Fig. 2 illustrates .a sectional in its extended position in dottedlines.

Referringnowgtothe drawing .in detail, the reference character 5 indicates the supportin legs of the incubator, which are positione under the respective corners of the incubator proper, and which are connected adjacent the lower ends thereof by the hori- Zontal connection members 6.

Supported on the upper ends of the supporting legs', is a substantially square table 7, forming the bottom of the lower section which includes side wall 8, and a hinged u per section 9 operating to close the top o the incubator, the same being hinged to one of the side walls 8 by means of the hinges 9.

The floor 7, ofthe incubator, is provided with Va centrally disposed circular opening 10, to the walls of which is secured the tubular flue 11, which extends upwardly Vfrom the bottom 7, and terminates at a point below the inner surface ofsection 9,to provide view taken y on line 2-2 of Fig. 1, and showing thelamp wardly and passing'through an opening 21 flue 11 and section 9.

' a clearance between the upper edge of the Disposedv within the incubator, and in spacedv relation with the ue 11, is a tubular member'12, the lower end of which is spaced from the bottom 7 of the incubator, to provide ai passageway between the lower end of the tubular "member 12 and the fioor,

whereby a circulation is setup between the flue 11 andthe tubular member 12 for distribut'ing the heat from the heating medium,

uniformly throughout the interior of the incubator.`

Arranged within the incubator proper, and spaced from the bottom 7 thereof, are the horizontaly bars. 13, which crossV each `other as at 14, for providing supports forVv lthe pins 15, which support the respective circular egg trays 16, and allow rotary movement thereof, with relation toY the iiicubator. l j

As shown, each` of the egg trays includes a circular base plate having integral upwardly extending flanges 17, provided with a central depression to receive the flexible connecting member 18, which has its ends l connected to one of the circular egg trays', in

such a way that movement of said egg tray will produce a relative and simultaneous vmovement of' all the eggjtrays supported within the incubator.

An operatingshaft 19, has its upper end Vconnected to oneof'the egg trays as at 20, the lower end `thereof extending Vdownformed in the bottom 7, and hasrconnection with the lcrank arm 22, to permit the lsaid egg tray to be rotated.

The substantially U-shaped supporting rods 23, have their upper ends secured to the under side of the bottom 7, in such a way thatV the same will be `free to swing laterally, for purposes to be hereinafter more fully described.

The lower ends24 ofthe U-shaped sup?v porting rods 23, are positioned between the lugs 25 formed on the under side of the lamp 26, whereby the lamp .26 is supported in proper relation with the flue 11. A rod 27,

has its upper end pivotally connected to thev under side of the lamp 26, as at 28, the lower endthereof being formed into a handle, and provided with notches 29 adjacent the lower endV of the handle, said notches adapted to engage overthe pins 30 and 31 secured to one of the horizontal members 6.

` l Shown as smaller at its top than at lthe* lower Aend thereofor ,the purpose Vof providing a which allowsthelampfto be swungtothe position as shown by Fig. '2, in dotted lines, the notch 29 on the opposite side ofthe rod beingfshownhas engagingthe pin 31, for supportingthe lamp in such'noperative po- ASition.

. lIt,Will/thus .be seen that after the lamp hasbien properly attended to, the sames easily swung back ,t'o its operative OStOXl, .,Where .the saine is prevented from spla- I nent,` due to. the engagement Vof' the notch, WiththepinBO. l

.The'lainp ,26, is provided withv the usual burner, and lamp-L globe, however, the lamp vglobe in this lparticular instance, vbeing passageway 32 between thelanip globe and the lower end of. the liuell, to permit fresh aiuto enter the incubator, Where the saine l I is heat/ed on its kpassage through the' vflue 1 1.

.In order that the 4operation of the lan-ip, .willlbe automatic, -I-have provided. a thermostat, whichl is located within the noubajor; any particularA point, the vthermostat o beingconnect'ed by means 'of the levers 33 with 'the movable .regulating 1 member 3 6,

pivoted-to lthe"burner prpper, theineinber edaptdvte moveover the, blaze of the lamp, for. cutting oil', v`or red u`c ing thesize of ltheameto regulate the heat wthuthe n- Qllbaton to maintain ,thesame at an even predetermined temperature.

Inpperationit is of course a known Vfact thatl theeggs 1Withinthe incubator must be moved with relation'to y.the source offbeat,

at predetermined interval and' inthe incubetersofknown construction, it necsi :saryto remove lthe top 'o1 j; op en theincuba- Vrotated with the result that the eggs Which .Were'previously positioned at agipointadjacent the source of heat supply, lare now moved "toV a position remote from the heat y supply. Y

AItwill be seen that since the'horizontal bars 13, are' .held Vin y spaced relation with fthe 'bottoni' of the lower section Y of the 1111- cubator, thatV the comp artinent; formed A'between the horizontal bars 13- andi-lmttom,A

maybe used for la nursery, for housingA the chicks, immediately after the hatching.

Having thus described my invention,what

I' claim` iszv A Y 1. In combination withan1incubator-hav ing a central ue, a plurality of circular trays rotatably 'supportedadjacentthe liuc,
